<h3>About MTI Industries &amp; Safe-T-Alert&trade;</h3><p>When you&rsquo;re miles from the nearest town &mdash; parked at a mountain overlook in your RV or anchored in a quiet cove on your boat &mdash; safety equipment isn&rsquo;t optional, it&rsquo;s essential. MTI Industries has built its reputation on exactly that principle. As the manufacturer behind the trusted <strong>Safe-T-Alert&trade;</strong> brand, MTI Industries specializes in propane, carbon monoxide, and smoke alarms designed specifically for the demands of recreational vehicles and watercraft.</p><p>Unlike household detectors that are engineered for climate-controlled, stationary environments, Safe-T-Alert&trade; alarms are purpose-built to endure the unique challenges of life on the road and water. According to the brand, their alarms are built to handle vibration, shock, humidity, and extreme temperatures encountered along the road, all while conserving battery power. That focus on environmental durability is what sets MTI Industries apart from general-purpose alarm manufacturers.</p><h3>A Full Line of Life-Safety Detection Products</h3><p>MTI Industries offers a comprehensive range of detection solutions, with products tailored for both RV owners and boaters. Their lineup includes standalone carbon monoxide alarms, dedicated propane/LP gas alarms, smoke and fire alarms, and popular <strong>dual-detection alarms</strong> that monitor for both carbon monoxide and propane gas simultaneously in a single, space-saving unit. Many models operate on hardwired 12V DC power &mdash; the standard electrical system found in RVs and boats &mdash; eliminating the need for battery replacements and ensuring continuous, uninterrupted protection.</p><p>For RV owners, Safe-T-Alert&trade; products are designed to meet RVIA (Recreational Vehicle Industry Association) and NFPA (National Fire Protection Association) standards, and select models are certified to UL 1484 and UL 2034 standards for propane and CO detection respectively. These certifications matter because they verify that a detector&rsquo;s performance has been independently validated against rigorous benchmarks &mdash; not just the manufacturer&rsquo;s own claims.</p><h3>Trusted by RV and Marine Communities</h3><p>Whether you&rsquo;re equipping a Class A motorhome, a fifth-wheel trailer, a pontoon, or an offshore vessel, MTI Industries offers a Safe-T-Alert&trade; model engineered for your specific environment. The brand&rsquo;s series-based product structure &mdash; from the compact 25 Series to the full-featured 85 Series &mdash; makes it straightforward to find the right level of protection for your application and installation requirements. From flush-mount designs for clean interior installations to surface-mount options for quick retrofits, there is a Safe-T-Alert&trade; format for virtually every setup.</p><p>Explore our full selection of MTI Industries <a href="/7469-mti-industries-carbon-monoxide-smoke-fume-detectors-200239">Carbon Monoxide, Smoke &amp; Fume Detectors for RVs</a> and <a href="/7469-mti-industries-carbon-monoxide-smoke-fume-detectors-201778">Carbon Monoxide, Smoke &amp; Fume Detectors for Marine applications</a> to find the right Safe-T-Alert&trade; alarm for your rig or vessel.</p>

Product Details

The MTI Industries 45742WT is a flush-mount dual alarm system designed to detect both propane (LP) gas and carbon monoxide (CO) in recreational vehicles. This 12-volt alarm upgrades single-function propane detectors to a comprehensive dual-sensor system, replacing Safe-T-Alert Model 40-442 propane alarms and other outdated units over 5 years old.

Key Features:

  • Dual detection technology monitors both propane gas and carbon monoxide levels simultaneously
  • Flush-mount design with black finish for clean, integrated installation
  • 12-volt DC power operation eliminates the need for battery replacement
  • Alarm mute button allows temporary silencing while ventilating the RV
  • Rapid recovery sensor automatically resets after silencing or reactivates if dangerous levels persist
  • Meets RVIA/NFPA safety requirements and conforms to UL 1484 standards for RV applications

Ideal for Class A motorhomes, Class B van campers, Class C mini-motorhomes, travel trailers, fifth wheels, truck campers, and folding campers. This alarm provides essential dual-threat protection with reliable 12-volt operation and professional-grade safety compliance for peace of mind on the road.

great easy to use and simple for a old man who cant use computer very well thank you

Had a little trouble finding the item needed. A search option would be helpful.

I recently ordered an Invidia N1 exhaust system from autoplicity and to be honest I was concerned at first my order was not shipped for 2 days, I know I was just very impatient. I'm not sure how their business works but 2 days of processing? I emailed their shipping department and got an email back explaining everything and it also said I would get an email today or the next day and sure enough I did! Had the lowest price for the part I was looking for. Also all the good reviews just made me want to order from this company plus the good prices you can't go wrong.

Quick&amp;easy

easy to navigate site and had the parts I needed at a reasonable cost.
